Looking for square plastic pots

I am looking for square plastic pots for my cacti & succulents like the ones in the following photos:

As you can see, they do not have “label slits” on the rim of the pots. I am looking for sizes of about 10cmx10cm, & preferably in orange/terracotta colour. I am in Sydney so a local supplier would be great, otherwise I am happy to do mail order if the pots are right.

I have looked high & low for these, so far without any success. Can someone please help?

Thanks in advance.

Ps: The photos, pots or plants are not mine. Thanks Pseudolithos for sharing the pics on Flickr.

As that is where I get all of the pots that I use for growing. They carry ones like the pots pictured in those photos at a reasonable price.

Thanks for the lead IXOXI. I think I've already contacted before, but I'll do so again..Best!

I have been buying all of my pots from here the only thing is you have to by in the pack size but they are cheap
